All-Dielectric Self-Supporting optic fiber cable ADSS
ADSS fiber optic cable adopts the layering structure of loose sleeve, 250 microns optical fiber is inserted into the loose sleeve made of high modulus material, the loose sleeve is filled with waterproof compound Loose casing (and filling rope) is twisted around non-metallic core reinforcement (FRP) to form a compact core, and the gaps in the core are filled with water and oil resistance paste The inner sheath of polyethylene (PE) is extruded from the cable core, and then aramid fiber is twisted to strengthen it Finally, the outer sheath of polyethylene (PE) or the outer sheath of resistance to electric mark (AT) is extruded
- Product introduction
·Product features
• no power failure
• AT sheath is adopted for excellent resistance to electric marks
• light weight and small cable diameter, reducing the impact of ice, wind and load on tower and support
• large span, with the maximum span exceeding 1000m
• excellent tensile and temperature properties
• life expectancy can reach 30 years
•Product application
Polyethylene (PE) sheath can be used for power lines of 10kV and 35kV. For 110kV and 220kV power lines, the distribution of electric field intensity must be calculated to determine the cable suspension point and the use of resistance to electric mark (AT) outer sheath. At the same time, the amount of aramid fiber and the perfect stranding technology are designed carefully to meet the application requirements of different spans.
·Product standards
ADSS cable complies with IEEE P 1222 technical standard and IEC 60794-1 standard.
